Show thata tho sun A minute parallax of about one sixtieth ot it a second of arc are found for arcturus by dr elkin gives alvea a most astounding result this small parallax implies a distance from the earth equal to about 11 oon times tho the suns distance this vast distance di i would produce it diminution of light of about 83 magnitudes so that tho the sun still placed at the distance of arcturus would be reduced to a star of magnitude it would nut not be visible mith an opera oper glassl g 1 ass 1 arcturus Is therefore in brouna round d numbers aj 0 magnitudes or over times brighter than the sun would be at the same distance assuming the same density and brightness of surface as the sun the diameter of arcturus would therefore be about seventy nine times the suns diameter or over miles mile 9 and its mass about times the mass of the sun figures well calculated to stagger the imagination Gent lemans magazine |
